Socket-weld Flange Steel Pipe Flange

Socket Weld Flange Our socket welding flange is designed for pipelines with small diameter and high working pressure. Generally, the diameter is not greater than 40mm and the working pressure shouldn't exceed 10.0Mpa. The production process of the socket welding flange is similar to that of loose flange. One end of the flange is welded together with pipe, while the other end is connected through thread.Available Sizes 3/8＂~3＂,DN10~DN80 Standards GB/T9112-2000 GB/T9117.1-2000 GB/T9117.2-2000 GB/T9117.3-2000 GB/T9117.4-2000 GB/T9124-2000 SH/T3406-1996 HG/T20592-2009,HG/T20614-2009,HG/T20615-2009,HG/T20623-2009, HG/T20635-2009 ASME B 16.5-2009 EN EN BS1560-3.1-1989 BS4504-3.1-1989 AFNOR NF E ISO JIS B2220-2004 Raw Materials Carbon steel:A105 Alloy steel:A182F 1-F 2-F 5-F 9-F 10-F 91-F 92-F 122-F 911-F 11-F 12-F 21-F 22 Stainless steel:A182 304-304H-304L-304N-304LN 316-316H-316L-316LN 321-321H 347-347H Low-temperature steel:A522 A707 Grade L 1-L 2-L 3-L 4-L 5-L 6-L 7-L 8 High-performance steel:A694 F 42-F 46-F 48-F 50-F 52-F 56-F 60-F 65-F 70F Pressure Grade American System:CLASS150 CLASS300 CLASS400 CLASS600 CLASS900 CLASS1500 European System:PN2.5,PN6,PN10,PN16,PN25,PN40,PN63,PN100.
